KNOCKDOWN ROLLER-SCREEN.

To all whom it may concern Be it known that I, WKILIAM W. NAT- son, acitizen of the United States, residing at the city of Jamestown, in thecounty of Chautauqua and State of New York, have invented certain newand useful Improvements in Knockdown Roller-Screens, of

which the following, taken in connection with the accompanying drawings,is a specification.

The invention relates to roller window screens; and th(- object of theimprovement is to provide a roller screen construction. which isknock-down in its arrangement, so that the. parts may he easily takenapart and put together. the difi'crent parts fitting one another soperfectly that they may be shipped l-1noclcdown and quickly and easilyadjusted to the. window frame. and when so adjnsted the springs may berel ased and they .are then in correct tension for the parts and readyfor operation; and the in- "ention consists in the combination andarrangement of the parts as shown in this speciliratimi and theaccompanying drawings and pointed out in the claims.

in the drawings. Figure 1 shows a "front elevation of the lower portionof a window frame having a roller screen mounted therein with the sa iin the raised position and the screen covering the space below the sash.Fig. 2 is a persperthe view of the lower end of one of the side cases ofthe screen frame showing the arrangement of the lower portion of thesame for the reception of the end of the. crosswise or sill casingcontaining the spring roll: and Fig. 3 is a perspective view of the endof said crosswise casing which lits into the lower end of the side caseshown in Fig. 2; and Fig. 4 is an elevation of said lower end of theside casing showing the position of the different parts. 5 and (5 showperspective views of the guide piece ior the end of the operating tapewithin the side case; and Fig. 7 is a sectional view oi tlie guide pieceat line X X in fFig. 6., showing the manner of attaching the tape.

The numeral 20 designates the window casing and the numeral 21 thewindow sash and glass.

The knoclcdown roller screen mechanism consists of two side cases 22which are precisely alike excepting they are rights and lefts. the lowerends 23 opening toward one another, as shown in Fig. 1. A crosswise rollcase 24 connects the side cases 22, as

"hereinafter set forth. Each of the side cases 22 consists of thelengthwise channel strip 25 and a cover strip 42, which are attached tothe Window frame or casing 20 by screws 26 through both strips. Theoperating pul- -stud is attached to the inner side of the channel strip25. The pulley 29 has a short square shaft or pin 31 extending therefromthen up over the top toward the opposite side case. An operating tape 32is attached to pulley 29 over two "spaced pins 72 by extending aroundand back beneath itself in locking engagement, and pulley 27. It is thenattached to a guide piece 33 which is slidably mounted within a channelor chute 34 in channelstrip 25, the channel being formed by means of asheet metal strip 35 which is attached lengthwise of the inner sideofthe channel strip 25. The pulley 29 must be of suflicient size toreceive over half of the operating tape when the screen is unrolled fromthe spring roll. Two guide pulleys 36.

' are preferably revolubly mounted on suitable studs, one just abovebottom pulley 29 and the other below top pulley 27 and have channelededges to hold the tape in line.

The guide piece 33 is preferably made in the form of a channel piecewith the two cross pins 37 therein a spaced distance apart, the same asin pulley 29, to receive the end ofthe tape32 around the same in thelocking. attachment shown in Figs. 7 and 20, which holds said tape endfirmly yet is easy of attachment thereto. .A slot 38 is provided throughthe inner side of the chan- I191 guide strip 33 to receive the headedstrip or pin 39 therethrough for attachment to thetop cross piece 40 ofthe screen fabric 41. The strip 39 is insertible into an openin the endof the top cross bar 40.

The lengthwise'partition or guide 'strip 35 also serves as a separatoror spacer between the channel strip 25 and the cover strip 42. The twostrips 25 and 42 are attached to-onc'anothcr by means ofscrews 43 whichpreferably engage through suitable holes in the cover strip- 42 with thebrackets 44 in .the channel strip 25 so that by-the removal of thescrews 43, the interior of the channel strip 25 and the operating tape32, the pulleys 27 and 29 are quickly exposed for repair.

edges, one flange 45- fitting over the outer flange-edge of the channelstrip 25, and ,the other flange edge 46 is held by the screws 43a-spaced distance from the inner flange edge 47 of the channel strip 25to thereby form thebpen channel slot 48 between the flanges .46 and 47to receive therein the .pin 39 in The cover strip 42 is formed withoppositely turned flanged lengthwise the guide strip 33 as it is mopedupward and downward in the raisingyand lowering of the screen 41.

A cap 49 is provided for the upper endof I the side case 22. The cap 49fits closely over the upper ends of the two strips 25 and 42, holdingthem firmly in position. The lower end of the cover strip 42 has theopen housing 23 formed thereon for the'reception of the crosswisehousing or roll. casing 24 for the sprin roller 52 to which thescreenfabric 41 is attached and upon which it isrolled. The casing part23 is attached at its upper end to the cover strip 42 by means of the.upturned lap 53 which is welded or otherwise attached to the flange '46of the holding the side casing 22 and the roller casing 24 firmlytogether and in position within the window frame, yet allowing a slightadaptation to the window frame. The housing or casing24-is simply atubular casing having preferably its. rear side 56 extending only partway up so as to permit the insertion of theroll 52 with-the screenfabric 41 attached and rolled thereon and providing an opening for thefree movement of the screen fabric 41 as it rolls out from and into thecasing 24 from the roll 38.

The roll'52 is preferably made from sheet metal tubing. An end plug 57is provided for each end of the tubular roller 52 formed to turn freelywithin the tube 52, and. has a square hole 58 in the outer end toreceive therethrough the square or rectangular pin or shaft 31 on pulley29 so as to turn with the pulley 29 in operatingthe tape 32 and thescreen 41.

The inner end 59 of the plug 57 .is diminished in size to fit the end ofa connecting tube 62 and has the slot 60 therethrough to receive the end50of the tension coil spring (ii in locking engagement. The connectingtube 62hascompensating notches 63 therein into which the ends 50 of thelocking springs 61 extend crosswise thereof in order to give a partialrotating compensating movement forthetnbe 62 and the tension s ring 61so that they will automatically a aphthe'm: selves to the movement orchanges in the tape 32 and screen fabric'41. A series of ho cs 64 arealso provided in thetubular end provided in the roller 52 in with holes64 to receiye a P111573 thereth ough indmlii- '12s plugs 57 for holdingthe tension of th springs 61'when said tension has been ad: justedasdesired, a series-of holes 65 being .iso

ing engagement to holdsaid spring tension until it is desired to releasethe same after the screen and easing have been properly set up, anopening 74 being provided in the case 2t through which the pin 73 may beremoved. The opposite end .31 of the tension spring til from thatengaging the slot tit) and compensating notch U3, is inserted through asmall opening (37 in the roller to thereby attach one end of said spring61 firmly to the tubular roller 52 while the other is attached to theinner end ofthe tubularplugfii'.

The cross piece 40 for the upper end of the screen fabric 41 ispreferably formed of an angle piece and a channel strip of'sheet metal68 which fits the angular projection of the cross piece 40 and bindsthereon a strip 69 preferably of rubber to form a weather strip whichpresses against the under side of the sash 21 thereby insuring theclosinq' of the space between the cross bar 40 an the sash 21.

The wrench (36 and locking plate T0 are provided for assembling orsetting up the roller screen mechanism and to insure the correct tensionthereon and are used in the following manner: The wrench tit; is used toturn the end plug-57 until the proper tension is obtained for thetension spring (31 and a pin 73 is then inserted through the openings 6%and thereby holding said spring 61 at the tension desired. liach of thetension springs til having thus been adjusted and the screen fabric 41having been attached to the roller by soldering or other suitable meansand the screen fabric rolled on the roller 52, the roller is insertedwithin the housing 24 and said housing and roller are then readv forshipment.

The tape 32 is attached to the guide piece 33 at one end and to theroller 2-) at the other and rolled on said roller 29 so that theguidepiece 33 preferably touches the upper end or cup 4.) of the sidecase as shown in Fig. 8, saidguide pieces 33 having the attaching stripor pin It!) inserted through the slot 38 and extending out through theslot 48 for insertion in the end of the cross bar 40. The cover strip-12 is then attached to the channel strips 25 by screws 43. and thelocking plate 70 is inserted through the lower end of the side case, thenotch 71 in the locking plate 70 fitting closely onto the square pin 31thereby holding the tape around the pulley E29 ready to receive thetension from s ring 61. The cross bar is attached to tile upper end ofthe screen fabric 41 preferably before it is attached to and rolled uponthe roller 52. The two side cases 22 and the roller case 24 are thenreadyfor shipment with the entire roller screen mechanism therein, andit is apparent that these three parts can he placed in an exceedinglysmall compass as compared with, the set-up figreen, whjle'all the thesquare openings 58 in the revolubleplugs 57 in each end of the roller52. The locking plates 70 are then withdrawn and the pin. T3. are alsowithdrawn from the holes ll-land (35 thereby applying the ten sion ofthe springs til to the screen through the plugs 5T. shafts 2H. pulleys 2tapes 3i, pulleys 27. channel guide strips 3 3, and conutcting pins Iiito the top cross bar 40 at the upper end of the screen fabric 41. Theside cases 22 are then attached to the sides of tin window casing 2ththe length of the pins t] and 225, and the ends permitting sutlicicntadaptation to insure a perfect fit within the window cnSltlg 20. Thetension springs 01 hold th tension firmly on the roller 3 and the screenfabric -11 so that the creen fabric may be manually raised or lmvered bythe cross bar -0 as desired. The compensating notches (:3 provide forthe unequal stretching of the wire 41 or the tapcslje.

The locking plates and the Wrench 66 are provided with each screen sothat it may be easily set up or taken down as desired thereby making aknock-down construction which is easily adjustable and operable.
